So, the same would be done with using "%s" and string() on the value?
:echo printf('%s', string([0, 1, 2, 3]))
[0, 1, 2, 3]
I suppose golang doesn't have a string() function.
An even simpler way is to do what Swift does:
"lead \(expression) tail"
With the example above:
"\([0, 1, 2, 3])"
I'm using this in Zimbu, works quite well.
